Abstract

The invention relates to a fuel injection pump for internal combustion engines having an injection onset adjuster with which the injection onset is adjustable toward "early", for instance in accordance with temperature. In accordance with the invention this adjustment toward "early" is made possible especially in pumps having a load-dependent injection onset adjustment, which preferably exhibit a shift toward "late" up to full load.
